WebJan 17, 2024 · 1. Companding is used to overcome quantizing noise in PCM in PCM transmitters, to allow amplitude limiting in the receivers to protect small signals in PCM from quantizing distortion. in PCM receivers, to overcome impulse noise. Answer: to overcome quantizing noise in PCM 2. The biggest disadvantages of PCM is its inability to handle … WebSep 26, 2016 · Companding refers to a technique for compressing and then expanding (or decompressing) an analogue or digital signal. For digital audio signals, companding is used in pulse code modulation (PCM) The process involves decreasing the number of bits used to record the strongest (loudest) signals

WebTranscribed image text: Question 40 2 Points In Europe, the ITU-T has established companding to be used to approximate true logarithmic companding. A) Digital … WebLet's assume 8 bits are used, so the number of quantization levels is 2^8 = 256. Thus, delta = 1.2/256 = 0.0046875 volts. To minimize the quantization error, we want to maximize the input signal range. The pre-amplifier should amplify the signal by a factor of 1/delta to maximize the input signal range. So, a1 = 1/delta = 213.333, and a2 = -1.2.
